How to measure the colour of coffee

Coffee is one of the most consumed beverages worldwide with over 400 billion cups being drunk every year. With the quality of instant coffee needing to keep up with its freshly brewed counterpart, every aspect of these drink granules need to be as good as they can possibly be to keep instant coffee popularity rising. Why are we analyzing appearance? When completing any analysis of colour and appearance it is important to know from the start why measurements are being taken. Are customers claiming a difference in colour and therefore consistence? Are samples of coffee being compared to the products […]

How to measure haze?

Recently, we receive many customer inquiries for haze measurement. We will introduce it today. Question: What kind of material need measure haze? Answer: Transparent and translucent plastic sheet, thin film, glass and other similar products need measure haze. For example, home glass, generally requires have a high haze. Because with haze, inner room will be bright; and people from outside can not see things inside the room. Question: What is haze? Answer: The haze we refer today is the transmission haze. The amount of light that is subject to Wide Angle Scattering at an angle greater than 2.5° from normal […]

Colorimeter and Spectrophotometer Questions and Answers

1. What is the instrument used for? Answer: Our instrument is designed for color measurement for any kinds of products. It can be used for color quality control for most industries. 2.What does L*a*b mean? Answer:L*a*b is the color space introduced by CIE (English name: International Commission on illumination, France name: Commission Internationale de l´Eclairage). L represents white or black (△L*+ represents too much white; △L*- represents too much black).a represents red or green (△a*+ represents too much red; △L*- represents too much green).b represents yellow or blue (△b*+ represents too much yellow; △b*- represents too much blue). You can refer to the […]

Whiteness and Brightness

Whiteness index is used for describing the whiteness degree of the material. The most commonly used whiteness indexes are ISO whiteness / ISO brightness, WI (Hunter) and WI (CIE)/WI (Ganz). What is ISO whiteness / ISO Brightness? ISO whiteness / ISO Brightness adopt single wavelength formula which means it adopts the reflectance value of single short wavelength band to represents the whiteness of material. It measures the short wavelength band’s blue diffuse reflection factor (R457). It is called ISO whiteness or ISO brightness. What is Hunter Whiteness Index? Hunter whiteness index adopts the concept of chromaticity is related to the […]

Difference between Colorimeter and Spectrophotometer

Both colorimeter and spectrophotometer can be used for color quality control. They are all belongs to color meters. Why they are called colorimeter and others call spectrophotometer. What’s the difference between them? And what’s the difference between their applications. We will introduce it. 1.What’s a colorimeter? What’s a spectrophotometer? Colorimeter is used for measuring the color difference value (Delta E) between two samples. Its accuracy is limited and can not tell the absolute L*a*b value, but it can tell theΔE. Because it can not tell the absolute L*a*b value, we can not exchange the test values with others. Spectrophotometer is […]

Spectrophotometers for Special Material Color Measurement

1.Powder Material Color Measurement Because of the different densities, sizes and shapes of powder materials will lead to different color measurement values. In order to avoid it, we can use a device to make powder into pellet. And then measure the pellet color, the result will be more stable and accurate. We can also use bench top spectrophotometer CS-800 which adopts D/8 geometry. It is with upward testing caliber to measure solid, pellet, powder and pasty materials much easier. 2.Semi Transparent Products Color Measurement For measuring color of semi transparent products, our benchtop CS-810 Transmittance Spectrophotometer is good choice. It […]
